Comparision Operators Examples in C++

In C++, comparison operators are used to compare two values or expressions and return a Boolean value (true or false) based on whether the comparison is true or false. C++ provides the following comparison operators:

  • Equal to (==): Returns true if the values on both sides of the operator are equal, otherwise returns false.
  • Not equal to (!=): Returns true if the values on both sides of the operator are not equal, otherwise returns false.
  • Greater than (>): Returns true if the value on the left side of the operator is greater than the value on the right side, otherwise returns false.
  • Less than (<): Returns true if the value on the left side of the operator is less than the value on the right side, otherwise returns false.
  • Greater than or equal to (>=): Returns true if the value on the left side of the operator is greater than or equal to the value on the right side, otherwise returns false.
  • Less than or equal to (<=): Returns true if the value on the left side of the operator is less than or equal to the value on the right side, otherwise returns false.
